The first 1000 copies of XXL come with a bonus disc taken from the rehearsal sessions. "Spicchiology? is the sophomore release from the supergroup XXL comprising all members of Xiu Xiu and Larsen. Recorded in late 2006 in Torino Italy Spicchiology? is the result of a profoundly creative friendship translated into music and spanning the globe."

"Ciautistico! is the debut album from XXL (Xiu Xiu Larsen), a collaboration between the Italian experimental cult band Larsen and James Stewart's mutated-pop project Xiu Xiu. Both groups consider their joint creative clash as a new band in itself more than just an occasional collaboration. Edited out of long and intense jam sessions the sound of Ciautistico! is totally schizophrenic, swinging between orchestrated pop songs, almost-techno beats and minimalistic droning tracks, but framed into a common melancholic mood and fronted by the inimitable James Stewart."
